Maintaining a full charge in an electric car as it travels around is a real challenge. The approach of electrifying the actual roadway is being explored in Korea.Physorg.com reports:
"In Daejeon, South Korea, the idea of a "recharging road" is being tested at the Korea Advanced Institute of Science and Technology. If the tests show that the idea is feasible (right now it's being tested on golf carts), charging strips would be placed in strategic places around town, embedded into the road surface. Electromagnetic induction would be used to charge the batteries of cars that contain a special magnetic, sensor-driven device. Powering the strips themselves would simply require a hook up to a standard electric grid. But if renewable power is the goal, it would also be possible to use solar power to provide the electricity needed for the charging strips." See full article.
